[0002] AGVs are transport vehicles equipped with electromagnetic or optical automated guidance devices, enabling them to travel along a predetermined guided path without human intervention. They offer safety protection and various transfer functions. AGVs are widely used in specific application scenarios in industries such as automotive, 3C electronics, semiconductors, medical, daily chemicals, and machining, performing tasks such as picking up parts and conducting inspections to meet customers' intelligent upgrade needs.

[0003] Because existing AGV transport vehicles have a one-piece structure and a large overall size, their large size prevents them from moving to areas with limited space for loading goods. Solving these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an omnidirectional transport AGV (Automated Guided Vehicle), which aims to solve the problem that existing AGV transport vehicles have an integrated structure, resulting in a large size and inability to move to areas with limited space for cargo loading.

[0005] This utility model is implemented as follows:

[0006] This utility model provides an omnidirectional transport AGV, including a transport mother vehicle, a transport daughter vehicle, and a guide rail. The transport daughter vehicle is disposed on the top of the transport mother vehicle, the guide rail is fixedly connected to the outer wall of the transport mother vehicle, a connecting component is disposed at the bottom of the transport daughter vehicle, and a support component is disposed on the outer wall of the transport mother vehicle.

[0007] The connecting assembly includes a connecting track, a base plate, a motor, a threaded rod, a moving part, and a limiting part. The connecting track is located on the top of the transport mother vehicle, the base plate is fixedly connected to the interior of the transport mother vehicle, the motor is fixedly connected to the top of the base plate, the threaded rod is installed at the output end of the motor, the moving part is slidably connected to the top of the base plate, and the limiting part is fixedly connected to the top of the base plate.

[0008] Preferably, the bottom of the connecting track is slidably connected to the top of the mother vehicle, and the top of the connecting track abuts against the bottom of the daughter vehicle.

[0009] By adopting the above technical solution, the connecting track can move on top of the transport mother car while simultaneously moving the transport daughter car.

[0010] Preferably, the threaded rod passes through the movable member and extends to the outside of the movable member, the outer wall of the threaded rod is adapted to the inner wall of the movable member through which it is passed, and the top of the movable member is fixedly connected to the bottom of the connecting track.

[0011] By adopting the above technical solution, when the motor drives the threaded rod to rotate, the moving part will drive the connecting track to move under the action of the thread.

[0012] Preferably, the limiting member is distributed on the front and back of the movable member, and the outer wall of the limiting member abuts against the outer wall of the movable member and is slidably connected to the outer wall of the movable member.

[0013] By adopting the above technical solution, the presence of the limiting component can effectively restrict the movement of the moving component, ensuring stability during the movement of the moving component and the connecting track.

[0014] Preferably, the support assembly includes an outer plate, a first movable component, an electric push rod, a second movable component, a slide rail, a limiting plate, and a stop plate. The outer plate is fixedly connected to the outer wall of the transport mother vehicle. The first movable component is installed on the top of the outer plate. The electric push rod is located on the outside of the transport mother vehicle. The second movable component is located at the bottom of the connecting rail. The slide rail is located at the bottom of the connecting rail. The limiting plate is located inside the slide rail. The stop plate is fixedly connected to the outer wall of the transport mother vehicle.

The presence of the abutment plate can limit the reset angle of the electric push rod.

[0019] The beneficial effects of this utility model are:

[0020] 1. By setting a connecting rail and a moving part at the bottom of the transport vehicle, the motor is controlled to rotate, causing the threaded rod to rotate. At this time, the moving part will move the connecting rail under the action of the thread, so that the connecting rail extends to the outside of the transport vehicle. Controlling the transport vehicle to operate at this time allows the transport vehicle to enter the interior of the storage bin through the connecting rail, making it convenient for operators to transport goods to the top of the transport vehicle. This solves the problem that the existing AGV transport vehicle is an integrated structure, which results in a large size and cannot move to areas with small spaces for loading goods.

[0021] 2. By installing an electric push rod and a limiting plate on the outside of the transport mother car, when the connecting rail moves, the limiting plate will move inside the slide rail. When one side of the slide rail abuts against the outer wall of the limiting plate and continues to move, the limiting plate will drive the electric push rod to adjust its angle through the second movable part, so that the electric push rod cooperates with the limiting plate to support the connecting rail and ensure the stability of the connecting rail.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Reference Figures 1-5 An omnidirectional transport AGV includes a transport mother vehicle 1, a transport daughter vehicle 2, and a guide rail 3. The transport daughter vehicle 2 is located on top of the transport mother vehicle 1, the guide rail 3 is fixedly connected to the outer wall of the transport mother vehicle 1, a connecting component 4 is provided at the bottom of the transport daughter vehicle 2, and a support component 5 is provided on the outer wall of the transport mother vehicle 1.

[0031] The connecting assembly 4 includes a connecting rail 401, a base plate 402, a motor 403, a threaded rod 404, a moving part 405, and a limiting part 406. The connecting rail 401 is disposed on the top of the mother car 1, and the bottom of the connecting rail 401 is slidably connected to the top of the mother car 1. The top of the connecting rail 401 abuts against the bottom of the daughter car 2. While the connecting rail 401 moves on the top of the mother car 1, it can drive the daughter car 2 to move. The base plate 402 is fixedly connected to the inside of the mother car 1. The motor 403 is fixedly connected to the top of the base plate 402. The threaded rod 404 is installed at the output end of the motor 403. The moving part 405 is slidably connected to the top of the base plate 402. The threaded rod 404 passes through the moving part 405 and extends to the moving part. The outer wall of the threaded rod 404 is adapted to the inner wall through which the movable part 405 is penetrated. The top of the movable part 405 is fixedly connected to the bottom of the connecting rail 401. When the motor 403 drives the threaded rod 404 to rotate, the movable part 405 will drive the connecting rail 401 to move under the action of the thread. The limiting part 406 is fixedly connected to the top of the base plate 402. The limiting part 406 is distributed on the front and back of the movable part 405. The outer wall of the limiting part 406 abuts against the outer wall of the movable part 405 and slides with the outer wall of the movable part 405. The presence of the limiting part 406 can effectively limit the movement of the movable part 405 and ensure the stability of the movable part 405 in the process of driving the connecting rail 401 to move.

[0032] By setting a connecting rail 401 and a moving part 405 at the bottom of the transport vehicle 2, and controlling the motor 403 to rotate, the motor 403 drives the threaded rod 404 to rotate. At this time, the moving part 405 will drive the connecting rail 401 to move under the action of the thread, so that the connecting rail 401 extends to the outside of the transport vehicle 1. At this time, controlling the transport vehicle 2 to operate allows the transport vehicle 2 to enter the interior of the storage compartment through the connecting rail 401, making it convenient for operators to transport goods to the top of the transport vehicle 2. This solves the problem that the existing AGV transport vehicle is an integrated structure, which results in a large size and makes it impossible to move to areas with small spaces for loading goods.

[0033] Support assembly 5 includes an outer plate 501, a first movable component 502, an electric push rod 503, a second movable component 504, a slide rail 505, a limiting plate 506, and a stop plate 507. The outer plate 501 is fixedly connected to the outer wall of the transport mother car 1. The first movable component 502 is installed on the top of the outer plate 501. The electric push rod 503 is located on the outside of the transport mother car 1. The first movable component 502 is rotatably connected to the bottom end of the electric push rod 503. The second movable component 504 is located at the bottom of the connecting rail 401. The second movable component 504 is rotatably connected to the top end of the electric push rod 503. The electric push rod 503 can be angled by the first movable component 502 and the second movable component 504. The slide rail 505 is open. Located at the bottom of the connecting track 401, the limiting plate 506 is disposed inside the slide rail 505. The outer wall of the limiting plate 506 is slidably connected to the inner wall of the slide rail 505. The bottom of the limiting plate 506 is fixedly connected to the top of the movable part 504. When the connecting track 401 moves, the limiting plate 506 can slide inside the slide rail 505. At the same time, the limiting plate 506 will drive the electric push rod 503 to adjust its angle under the action of the slide rail 505. The abutment plate 507 is fixedly connected to the outer wall of the transport mother car 1. The outer wall of the abutment plate 507 abuts against the outer wall of the electric push rod 503. The presence of the abutment plate 507 can limit the reset angle of the electric push rod 503.

[0034] By installing an electric push rod 503 and a limiting plate 506 on the outside of the transport mother car 1, when the connecting rail 401 moves, the limiting plate 506 will move inside the slide rail 505. When one side of the slide rail 505 abuts against the outer wall of the limiting plate 506 and continues to move, the limiting plate 506 will drive the electric push rod 503 to adjust its angle through the movable part 504, so that the electric push rod 503 cooperates with the limiting plate 506 to support the connecting rail 401 and ensure the stability of the connecting rail 401.

[0035] The working principle of this omnidirectional transport AGV is as follows: When the transport vehicle 2 needs to enter the storage compartment, the operation of the motor 403 is controlled, causing the threaded rod 404 to rotate under the action of the motor 403. At this time, the moving part 405 will move under the action of the thread, and drive the connecting rail 401 to move, so that one end of the connecting rail 401 extends into the interior of the storage compartment. At the same time, when the connecting rail 401 moves, the limiting plate 506 will move inside the slide rail 505, and drive the electric push rod 503 to adjust the angle. The electric push rod 503, together with the outer plate 501, supports the connecting rail 401 and controls the transport vehicle 2. At this time, the transport vehicle 2 will enter the interior of the storage compartment through the connecting rail 401.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
